You will need:

• Four different colors of yarn (I use aran weight organic cotton yarn (Lana Grossa Organico) but you can use whatever you like).
• Crochet hook as suggested on your yarn label or a little bit smaller. (To achieve a tight gauge with the yarn.) I use 3,5 mm (4/E) hook , but 5 mm (8/H) is suggested on my yarn label.
• Stuffing
• Little bit of black thread for embroidering the face
• Yarn needle

Finished flasks are about 2.6” (6 to 7 cm) wide and 4.2” (10 to 11 cm) high.
